SSP support has been added to ports with WITH_SSP for i386 and amd64
on FreeBSD 10, and amd64 on earlier versions.
SSP_UNSAFE is added to disable in a port if it fails to build, but
this should only be used in rare circumstances such as kernel modules.
Otherwise, the port may just be failing due to lack of respecting
LDFLAGS.
On FreeBSD 10, this uses an ldscript in /usr/lib/libc.so to pull in
libssp_nonshared.a to address issues linking on i386 [1].
On earlier FreeBSD versions the WITH_SSP knob will add -lssp_nonshared
to LDFLAGS on i386. This is not needed on amd64. However, several hundred
ports do not currently respect LDFLAGS, so this support is disabled currently
as it causes build failures if a dependency is looking for the stack_chk

Update to latest GNUstep core libraries.
Update dependent packages with more recent releases.
Remove old and bit-rotted ones.
Switch to using clang 3.3 and libobjc2 1.7 by default, so modern Objective-C
features work out of the box and remove a lot of configurable options for
sub-optimal (and, often, unsupported / deprecated upstream) configurations.
Take maintainership of GNUstep-related ports.
Several of the ports left in have scary warnings which mean that they are likely
broken in lots of cases. Future commits will fix them.

Replacement for the GNU Objective-C runtime supporting the features
of Objective-C 2 for use with GNUstep and other Objective-C programs.
This runtime is based on the Etoile Objective-C Runtime, an earlier
research prototype, and includes support for non-fragile instance
variables, type-dependent dispatch, and object planes. It is fully
compatible with the FSF's GCC Objective-C ABI and also implements
a new ABI that is supported by Clang and is required for some of
the newer features.
